Garden heliotrope
From Citizendium, the Citizens' Compendium
The garden heliotrope is actually a range of hybrids in the genus Heliotropium, mostly derived from H. arborescens. They may grow to over 6 feet tall but dwarf varieties are more popular, planted as garden borders or in pots and window boxes.
They are best grown in moist but well-drained soil, in full sun. They are planted in the spring. While some varieties are perennials, and may be grown in temperate zones, none can tolerate frost well.
